And you’re converting the Excel file to a CSV file? If so what does the raw CSV look like?
Cheers.
Importing users
KevinTheJedi yes convert it to csv extension
Still the same in excel
Only accept it in English language but error in Arabic language
I think the issue is the fields are backwards due to Arabic being RTL. Try switching the order of the fields to LTR and retest.
Cheers.
KevinTheJedi in which csv file or import form
Heba CSV file
'Unable to map header to the object field"
What's the error??
Can I export csv file from app. And then import it again with the users?
Ok done ,, many thanks 
After import the data not appeared in user 
Then it seems like the CSV was malformed, the data was incomplete, your browser is hard-caching, or the import died/timed out. No way to tell unless you see any errors anywhere (general server logs, webserver error logs, PHP error logs, MySQL/MariaDB error logs, osTicket System Logs, Browser Console logs, etc.).
Cheers.
Is there a limit to users imported ?
Can I make Email field not a mandatory field?
Is there a limit to users imported ?
This would only be limited by the server and PHP configuration. On the osTicket side you can import as many as you want.
Can I make Email field not a mandatory field?
No, our system is an email-based system and each user and agent have to have a unique email address. We use the email address as the unique identifier.
Cheers.
Okay many thanks for you 
Pls in case of changing email of users after registration
is The tickets created on oldest email tracked to now email or not?
Can I add clickable icon for social media in os ticket interface 
You must customize the codebase to accomplish this. There are no guides on customizations so you are on your own.
Cheers.
